Halloween isn’t just for kids going trick-or-treating! In fact, every year, celebrities get SUPER into the holiday while attending star-studded bashes, and 2018 was no different. Tons of stars dressed up in epic costumes to celebrate the holiday, and we rounded up the best of the best right here. While most celebrity costumes are shown off on their Instagram pages, many are also captured by paparazzi as the stars head to parties and other events to celebrate.

Here, Paris Hilton arrives at Matthew Morrison’s annual Halloween bash in West Hollywood. She dressed as a super sexy butterfly, wearing a bejeweled corset bodysuit, paired with matching, massive wings and feathers atop her head. Paris really went all out with her look by also adding a pair of butterfly glasses, along with some knee-high, pastel blue boots with pink laces that went perfectly with the rest of the look.
